MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Feb. 8, 1910.

Divided and this application filed February Serial No. 478,659.

To all whom it may concern:

Be it known that I, HARRY C. GAMME- run, a citizen of the United States,residing at Bratenahl, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Mechanical Movements,of which the following is a full, clear, and exact description,reference being bad to the accompanying drawings.

The object of this invention is to provide an efficient and compactmechanism for the transmission of motion.

The mechanism herein shown is adapted for use in a variety of relations,but finds its highest efliciency when used where economy of space,lightness of construction, and re duction from a high to comparativelylow speed are required. Such conditions arise in the construction ofmachines for aerial navigation, and occur in many other machines.

The present application is a division of my application No. 396,546, fora flying machine, where this driving mechanism is shown as operating thewings of an orthopter.

Generally speaking, the invention comprises the elements andcombinations thereof set forth in the accompanying claims.

Reference should be had to the accompanying drawings, in which Figure 1is a side elevation of a mechanism embodying my invention; Fig. 2 is anend elevation of the showing in Fig. 1; Fig. 3 is a side elevation ofthe controlling clutch, driving wheel and a section of a main portion ofthe driven gear; Fig. 4 is a detail showing in section the main gear andbearing ring.

Any suitable support or frame may be employed as a mounting for thevarious parts of the mechanism, and for the purpose I have shown a framecomposed of tubular members suitably joined together to form a rigidstructure.

A ring 2 is formed in two parts, which are secured together by the ears3 and 4, through which bolts 24 pass, and these ears are secured bysuitable clips or other fastening means to the bars 5 and 6 forming apart of the frame. The ring is also held against relative movement byits engagement with a bar 7 which forms a part of the frame, and ifdesirable, the ring may be secured at other points. \Vithin the ring 2is mounted the main or driven gear 8. This gear has a groove 9 seatingdirectly over the ring and in the adjacent faces of the ring and grooveis an annular ball raceway in which is held a complete circle of balls10. This makes a very simple and effective ball bearing for the gear 8,the balls being put in place before the ring-halves are fastenedtogether. The gear 8 is provided with a double set of gear teeth 11 and12 on opposite sides of the ball groove 9. A driving shaft 18 extendsoutside the ring and is mounted at one end in the bearing block 14 whichis securely mounted upon the ring 2.

-Upon this shaft are secured pinions 15 and 16 which when assembled inoperative relation to the gear are on opposite sides of the block 14 andengage with the two rows of teeth 11 and 12 upon the gear.

Pitmen 20 and 21 are pivotally mounted upon the gear at diametricallyopposite points. These pitmen are in turn c011- nected with members 22and 23, which as shown are pivoted upon the frame, butsuch anarrangement is not necessary, as the members 22 and 23 are simplyrepresentative of any members through which motion is transmitted to anydevice or mechanism it is desired to operate. The pitmen preferablyconnect with opposite sides of the gear to make a proper balance. Whiletwo pitmen have been shown, it will be understood that more may be usedwhere desirable, care being taken that the same are mounted upon thegear in such relation to each other that a condition of balance willalways be obtained.

The shaft 14 is driven in any desired manner, and for the purpose I haveshown two engines 17 and 18 which are mounted within the frame. It isevident that other forms of motors may be used than that which is shown,and I do not limit myself in this respect. The shaft 13 may be connectedwith and disconnected from the engine by means of a suitable clutchmechanism which is represented by the outer fly-wheel member and theinner conical member 19 in engagement therewith and freed by movementtoward the engine.

From the construction above described a mechanism is obtained that islight, and yet strong and which is adapted to transmit motion with highefficiency.

Having thus described my invention, what I claim is:

1. The combination of a ring, a wheel journaled within and by means ofsaid ring and overhanging it on both sides and having gear teeth on itsoverhanging portions, and two pinions engaging with said teeth fordriving said wheel.

2. The combination of a ring, a revoluble member j ournaled within saidring and having gear teeth upon the outer periphery thereof, a pinionengaging with the teeth for driving said member, a pitman connected withsaid member, and driven means to which said pitman is connected.
